  1. 1. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Oskar Sundberg; [2023]
    Nyckelord :geothermal energy; geothermal resource assessment; geothermal potential; volume method; volumetric method; recovery factor; direct use; direct heat; Mesozoic aquifers; Earth and Environmental Sciences;

    Sammanfattning : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. LÄS MER

  3. 2. Wildfire growth modelling in Sweden - a suitability assessment of available data

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Henrik Hagelin; [2023]
    Nyckelord :Geography; GIS; Geographic Information Science; Physical geography; Prometheus; WiSE-FASS; The 2014 Västmanland wildfire; Wildfire growth modelling; Wildfire suppression support; Wildfire behaviour; MESAN; Earth and Environmental Sciences;

    Sammanfattning : Wildfires are worldwide problems that stress societies by damaging their economies and they cause serious, sometimes fatal, health implications among the populations. In recent years, the rate of wildfire occurrence has increased as the global average temperature has risen. Because of global climate change, this rate is expected to continue rising. LÄS MER

  4. 3. COMPARATIVE ANALYSIS OF MACHINE LEARNING LOAD FORECASTING TECHNIQUES

    Magister-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Humphry Takang Bate; [2023]
    Nyckelord :;

    Sammanfattning : Load forecasting plays a critical role in energy management, and power systems, enabling efficient resource allocation, improved grid stability, and effective energy planning and distribution. Without accurate very short term load forecasting, utility management companies face uncertain load patterns, unrealistic prices, and poor infrastructure planning. LÄS MER

  5. 4. Spatial downscaling of gridded soil moisture products using optical and thermal satellite data: the effects of using different vegetation indices

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Tómas Halldórsson Alexander; [2023]
    Nyckelord :Physical Geography and Ecosystem Analysis; Remote Sensing; Soil moisture; Downscaling; Vegetation index; Earth and Environmental Sciences;

    Sammanfattning : Soil moisture (SM) plays an important role in the exchange of heat and water between the surface and atmosphere, impacting water and energy cycles and the climate. Satellite remote sensing offers a global-scale estimation of SM; however, the coarse resolutions of satellite SM products, typically ranging from 25-50 km, are unsuitable for regional analysis.

  7. 5. Temperatur- och flödesberoende beteende i anslutning till lek hos harr (Thymallus thymallus) i Indalsälven

    Master-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Daniel Sjöström; [2023]
    Nyckelord :spawning; breeding; grayling; temperature; flow; behaviour; season; hydroelectric power; hydropeaking; waterways; wind power; green energy; shallow; grayling population; spawning period; incubation; temperatur; temperaturberoende; flöde; flödesberoende; beteende; lek; harr; thymallus thymallus; indalsälven; järkvissle; korttidsreglering; vattenkraft; lekdjup; inkubation; flödesreglering; flödesregim; harrbestånd; ståndplats; handpejling; lekperiod; lekbeteende; konnektivitet; vandringshinder; fragmentering;

    Sammanfattning : Vattenkraftens påverkan på rinnande vatten är välbeskriven i litteraturen. Med ökat intresse för vindkraft och andra energislag med begränsad klimatpåverkan, ökar även behovet av reglerkraft. Effekten av korttidsreglerad vattenkraft på ekosystem är ett aktuellt ämne med kunskapsluckor i stort behov av fler studier. LÄS MER
